Testosterone’s Effects on Erectile Dysfunction

Testosterone is the primary sex hormone produced by males. Without having normal or high levels of testosterone, the male sex drive is almost non-existent. Testosterone levels are commonly thought to have an effect on erections, but is this a myth?

Testosterone levels usually do not effect erections

Erectile dysfunction has many causes, but low testosterone levels usually are not one of them. While low levels of testosterone can play a factor, it is not the leading cause. Low testosterone, however, can make erectile dysfunction worse.

If testosterone levels aren’t causing erectile dysfunction, what is?

Erectile Dysfunction has a long list of potential causes that are both physical and mental ailments. Potential causes include:

  • High Blood Pressure
  • Heart Disease
  • Insomnia
  • Medications
  • Alcoholism
  • Diabetes
  • Depression
  • Anxiety

So low testosterone has no effect on my sex life?

Wrong! While low testosterone does not cause erectile dysfunction, it does cause a reduced sex drive. A reduced sex drive can cause a lack of interest in sex altogether, which also makes it more difficult to gain an erection.


It is natural for testosterone levels to decrease with age. However, growing old is not the only cause. Lower testosterone levels can be caused by:

  • Injury to the testicles
  • Radiation treatment for cancer and other diseases
  • Dysfunction of hormonal glands
  • Medications
  • Genetic abnormalities

If any of the above scenarios apply to you, getting familiar with the symptoms of low testosterone might be a good idea.

How do I know if I have low testosterone?

There are quite a few symptoms associated with low testosterone. A few of these are:

  • Loss of muscle mass
  • Decreased energy
  • Decreased sex drive
  • Decrease in the amount of body hair
  • Sudden changes in cholesterol levels

While these symptoms may indicate that you have low testosterone, there is no way to tell unless you get tested by your doctor. 


If the only cause for your decreasing enjoyment of sex is the loss of sex drive, then yes! Higher testosterone levels will increase your interest in sex, making it easier to gain and maintain an erection. 


Having high testosterone levels is not a bad thing! Having naturally high testosterone levels is rare, but it does occur. It is most common in individuals that have undergone treatment for low testosterone.

While there are a few studies discussing the short-term effects of high testosterone, not a lot of information exists regarding long-term high testosterone levels.

Some benefits provided by having high testosterone are:

  • Increased muscle gain
  • Increased fertility
  • Increased sex drive
  • Increased energy

Testosterone therapy does have risks associated with it and it affects every individual differently. Consult with your doctor before beginning any form of testosterone therapy.
